5.
Select or clear
Secure Media Allocation
. If enabled, Secure Media Allocation ensures that
media allocated to the storage domain always remains in the storage domain. Even if all
data on the media is deleted, the media will not be reallocated to another storage
domain.
Note:
Secure Media Allocation should only be enabled when, for compliance purposes,
the user must be certain which media ever contained any data for the storage
domain (usually, to physically destroy the media once the data is no longer
needed), or to force rotating through media when new backups are created and
old backups are deleted.
6.
Select the
Write Optimization
for the storage domain.
This setting specifies whether job chunks are written as quickly as possible or across as
few pieces of media as possible. For example, when
Performance
mode is set for a tape
partition, job chunks are written as quickly as possible, using all tape drive resources,
even if that means that more tapes are allocated to the bucket than are necessary to write
the data.
It is better to use
Capacity
mode if you plan to eject the tapes after the job completes or
if the bucket is written to very rarely and capacity in the library is of concern.
Performance
mode is recommended for tape partitions in all other cases.
Storage domains for pool partitions should generally have a
Capacity
write optimization
because pools are very fast and under less contention. It is rare for a pool storage
domain to benefit from
Performance
mode.
